for the lamp carrying element whereby an electric conductor oryconductors maybe ca'rs' i'ied-in the support without danger of becominginjured when the support is adjusted in various positions.

Other objects ofmy 'invention not hereinbeforepointed'out will appearfrom the following detailedY description and the claims,

taken with an inspection of the accompany- 30 v ing drawings, in which-Figure 1 is a perspective view ofa lightV support embodying theimprovements of myV invention; e
